Portable terminal

1. A portable terminal, comprising: a body; and an input part on the body, the input part having a changeable position, wherein the input part includes a sliding part slidable along a lateral surface of the body without triggering transmission of any signal to the body, and wherein the input part is rotatable 360 degrees along an entire circumference of the body.

2. The portable terminal as claimed in claim 1 , wherein the input part includes: the sliding part slidable along a guide, the guide being on the side of the body; a button part on a first side of the sliding part, the button part sensing a user input and generating the input signal; a transmission part on a second side of the sliding part, the transmission part transmitting the generated input signal to the body; and a receiving part on the body, the receiving part receiving the input signal from the transmission part.

3. The portable terminal as claimed in claim 2 , wherein: the guide includes guide protrusions, and the sliding part includes guide grooves, the guide grooves being slidably combined with the guide protrusions.

4. The portable terminal as claimed in claim 3 , wherein the guide protrusions have a thickness corresponding to the guide grooves.

5. The portable terminal as claimed in claim 2 , wherein: the guide includes guide grooves, and the sliding part includes guide protrusions, the guide protrusions being slidably combined with the guide grooves.

6. The portable terminal as claimed in claim 5 , wherein the guide protrusions have a thickness corresponding to the guide grooves.

7. The portable terminal as claimed in claim 2 , wherein the sliding part includes a flexible material.

8. The portable terminal as claimed in claim 2 , further comprising a plurality of button parts.

9. The portable terminal as claimed in claim 2 , wherein the button part and the transmission part are on opposite sides of the sliding part and facing each other.

10. The portable terminal as claimed in claim 2 , wherein the input signal is transmitted upon contact of the transmission part and the receiving part.

11. The portable terminal as claimed in claim 10 , wherein the button part is formed at the one side of the sliding part in a protruded form.

12. The portable terminal as claimed in claim 11 , wherein the transmission part and the receiving part are conductive.

13. The portable terminal as claimed in claim 2 , wherein the button part is a touch switch.

14. The portable terminal as claimed in claim 2 , wherein the button part is a capacitive touch switch.

15. The portable terminal as claimed in claim 2 , wherein the button part is a resistive touch switch.

16. A portable terminal, comprising: a body; and an input part on the body, the input part having a changeable position, wherein the input part includes: an input part on the body, the input part having a changeable position regardless of its operational state, wherein the input part includes: a sliding part slidable along a guide, without triggering transmission of a signal to the body and without changing a state of an input signal, the guide being on a side of the body; a button part on a first side of the sliding part, the button part sensing a user input and generating the input signal; a transmission part on a second side of the sliding part, the transmission part transmitting the generated input signal to the body; and a receiving part on the body, the receiving part receiving the input signal from the transmission part, and the sliding part is a continuous member along an entire circumference of the body.

17. The portable terminal as claimed in claim 2 , wherein the sliding part is slidable along the lateral surface of the body independently of a connection between the transmission part and the receiving part.
